WebSelective Catalytic Reduction (SCR) is an advanced active emissions control technology system that reduces tailpipe emissions of nitrogen oxides (NOx) down to near-zero levels in newer generation diesel-powered vehicles and equipment. The SCR system involves several components packaged together with other parts of the emissions control system. WebOct 5, 2024 · Here the SCR is triggered by dumping the capacitor charge into the gate for the positive half cycle. For the negative half cycle the capacitor charge is clamped by the 1N4148. This means for both half cycles the capacitor is charged from the discharge level (typically about 1.5 V) achieved at the last trigger.
